I suffer from a sickness called adrenal deficiency, I am not able to stop medication and either to take them without food. It is a very serious sickness that has no cure. Do I need to make the fast of the 9 of Av?.
This year Tisha Bav falls out on Shabbos and is pushed off until Sunday. in such a scenario an ill person may eat and take whatever medicine necessary. In other years what needs to be determined is what will happen if you fast for a day and don’t take the medicine. If it will make you slightly ill you may need to fast. if it makes you severely ill or puts you in any danger, you may certainly eat and take the medicine.
